Firmware release 1.7.1.b1
-
@daniel Making runs in unresolved libs:
- micro-ecc
- jsmn
- soc
I freshly cloned pycom-esp-idf to overcome compile errors, but these libs are missing during the link state.
So: Where do I get the libs from?
Update: So, libmicro-ecc.a is in the lib directory, only the Makefile for the bootloader needs a --Llib in the definition of B_LIBS. But still libjsm.a and libsoc.a are missing.
Update 2: Fixed with an update to the repository by Daniel -
Hi,
The previous code built easy enough... seems like this one's bootloader has some overlapping names defined already in IDF. Do you have any suggestions for how to build this version?
Thanks,

@mcook did you also clone the latest version of the IDF: https://github.com/pycom/pycom-esp-idf ? With the old IDF it is not going to build...

I pulled again, and I got those libs.

Thanks, it went a lot further this time. I was able to build the bootloader. But it is failing while trying to build the app. Seems like a lot of it was completed.
I am getting a number of errors. Do you have any suggestions?

@mcook did you include the board name in the make, like
make BOARD=WIPY TARGET=app -
Yes. I did. I use the flash target to get it to write directly to the board.

@daniel
I have few new problems after upgrade from 1.6.13 to 1.7.1
Now many times i gotAttributeError: 'module' object has no attributebut code was not changed and worked before upgrade - can something e.g.
GC root pointerschange affect some code?
I do not use custom threads. Only "simple" code.UPDATE
After downgrade to 1.6.13 all work ok without any change in the code.. -
@livius: can you share a small piece of code that reproduces the issue that you are having? Thanks...
-
@mcook please try clonning the new IDF from scratch.
-
@livius can you share the complete exception log? Is it happening inside an interrupt callback?
-
Hi. I did that.
These are my steps. They worked with the previous source. But now I am receiving the error. Do I need to change something?

Is it happening inside an interrupt callback?
I do not use in this project callbacks and threads
i have tried to create
minimal codeto reproduce but still without success.
Maybe this help somehow - but probably not:

@mcook
not sure if it helps but the latest toolchain is actually https://dl.espressif.com/dl/xtensa-esp32-elf-osx-1.22.0-61-gab8375a-5.2.0.tar.gz -
@daniel
i have found problem :) And now have question.Is name
wifiregistered as reserved unit name?
i have in my lib folderwifi.pybut i see that when i call dir it list me some system objects?
>>> dir(wifi) ['Wifi', 'WLAN', '__name__', 'hexlify', 'sleep', 'Timer', 'exc_info', 'start_new_thread']after changing
wifi.pyto different name and all its references
all work ok -

I was just reading this post about the 4MB pSRAM support https://www.esp32.com/viewtopic.php?f=13&t=2031As Jeroen explains do we need to build the toolchain from the xtensa-1.22.x-ext_ram_patch branch to compile the Pycom source correctly for the W01/L01 modules?
All seems a bit cutting edge :-) but to get 4MB RAM wow...
